7000 Series/High Reliability Reed Relays
High Reliability Reed Relays
The 7000 Series is ideally suited to the needs of Instrumentation, Data
Acquisition, Process Control, Telecommunications and General Purpose
requirements. The specification tables allow you to select the appropri-
ate relay for your particular application. These models are specifically
designed for high quality and reliability with versatile switching
capabilities and contact forms. If your requirements differ, please
consult your local representative or Coto’s Factory to discuss a custom
reed relay.

Environmental Ratings:
Storage Temp: -35°C to
+100°C;
Operating Temp: -20°C to
+85°C
Solder Temp: 270°C max; 10 sec. max
The operate and release voltage and the coil resis-
tance are specified at 25°C. These values vary by
approximately 0.4%/°C as the ambient temperature
varies.

These relays contain bias magnets. Correct coil polarity must be observed.
Coil suppression diode is required for proper operation. Correct coil polarity must be observed.
Break before make not guaranteed.
Dot stamped on top of relay refers to pin #1 location. E-pin indicates Electrostatic shield pin. Unused pins omitted.
Pin numbers for reference only.
All models with Hg wet contacts are position sensitive, must be mounted within 30
o
of vertical plane. See schematic.
Model #7003-5193 represents a complete part number.
